TAXD10M2GLDBET2S 产品概述

一、产品简介
TAXD10M2GLDBET2S 是由 YJX(雅晶鑫)生产的全国产 HC-49S 直插型晶振,标称频率 10.000 MHz,面向通用数字时钟、通讯与测量设备等需要稳定参考频率的场合。器件采用标准 HC-49S 插件封装,适合手工焊接与波峰/回流焊后插件工艺,便于维修与替换。

二、主要技术参数

  • 型号:TAXD10M2GLDBET2S(YJX / 雅晶鑫)
  • 封装:HC-49S(直插 / 插件)
  • 频率:10.000 MHz
  • 常温频差(初始容差):±20 ppm(室温标称)
  • 负载电容:20 pF(标称)
  • 频率稳定度(随温漂动):±30 ppm(典型/规范)
  • 等效串联电阻(ESR):80 Ω
  • 工作温度范围:-20 ℃ ~ +70 ℃
  • 用途:时钟源、微控制器/FPGA 时钟、通信本振、测试设备参考等

三、产品特性与优势

  • 稳定性好:常温下频差小(±20 ppm),结合温度稳定度(±30 ppm)可满足多数中高精度时钟需求。
  • 兼容性强:标准 HC-49S 插件形式,直接替换传统直插晶振,便于装配与维护。
  • 可靠性与国产化:全国产制造,供应链可控,适合批量采购与长期维护。
  • 适用电路广:适配常见的 Pierce 型或反相器振荡器结构。
  • 机械性能稳健:直插封装抗振性和机械强度优于贴片薄型器件,适合需要人工装配或现场更换的场景。

四、典型应用场景

  • 单片机、微处理器和 FPGA 的系统时钟源;
  • 串口、以太网、无线设备与通信基带模块的本振参考;
  • 实验室测试与校准设备;
  • 工业控制器、计量仪器与嵌入式设备的时间基准。

五、使用与安装建议

  • 负载电容匹配:该晶振标称负载电容为 20 pF。若采用对称两端接地的外部电容 C1、C2,且两端电容相等,则可用近似关系 C ≈ 2 × (CL - Cstray) 来估算外部电容值(Cstray 为电路走线及器件的寄生电容,典型为 2–5 pF)。例如在寄生电容 2 pF 时,C ≈ 36 pF,可选用 33 pF 或 39 pF 的标准值并做实际调试验证。
  • ESR 考虑:等效串联电阻 80 Ω 属中等数值,可能对某些振荡器电路的启动性能有影响。选用时请确认所配用的驱动器/反相器有足够的环路增益和驱动能力,以保证快速可靠起振。
  • 走线与布局:尽量缩短晶体引线到振荡器输入的连接长度,减少寄生电容与干扰。布线时避免高频信号线与电源开关噪声靠近振荡器回路。
  • 焊接与环境:HC-49S 适用于手工焊接与波峰/回流后插件工艺,焊接温度和时间请参照厂商的焊接规范以避免频率漂移或内部应力。工作温度范围为 -20 ℃ ~ +70 ℃,该温区适合商业与一般工业环境,但在更极端温度下需选择专用温度等级的晶体。

六、品质与采购提示

  • 供应与替换:作为全国产产品,适合需要国产化替代或长期供货保障的项目。批量采购时建议索取出厂检验报告(频率、频差、ESR、温漂曲线)以便验证一致性。
  • 样品验证:在正式放量生产前,建议进行样品测试,包括启动时间、频率偏差在目标电路中的表现、在工作温度范围内的漂移等,以确保符合系统需求。
  • 包装与存储:遵循厂家包装与存储要求,避免受潮、受震或长时间高温存放导致性能退化。

七、总结
TAXD10M2GLDBET2S(10 MHz,HC-49S,20 pF,ESR 80 Ω,-20~+70 ℃)为一款面向通用时钟应用的国产直插晶振,具有良好的频率稳定性与国产供应优势。合理匹配负载电容并注意振荡器电路设计与布线,可以在多数嵌入式、通信和测试设备中可靠使用。若需更详细的性能曲线或定制规格,请联系雅晶鑫(YJX)技术支持获取数据手册与样品。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
